Hello,
I thought I already post it but I have searched for this question and have not found it
So,
I would like to use my athena as a voip phone.
All is working yet, but:
My wifi turn off when the screen does.
There must be an issue to force the wifi to stay on. I am not good in registry edition, but may I have some advice?
Where does power management is define?
Why bluetooth stays on despite the screen is off and the wifi does not?
I thank you and, sorry for my english!
The short answer is that this is not possible - WiFi is such a drain on the battery that it would run flat in aboit 2 hours if allowed to stay on.
The only workaround would be to keep the device connected to mains power, then disable all power saving; you may get away with using a screen blanking utility and then disabling power saving, but our previois tests suggest that even blanking the screen tutns WiFi off.
For reliable VOIP receiving, you should be using the 3G data connection.
I would like my gtablet to remain able to establish ssh connections
after the display turns off.
It appears even if I set the wifi preference to never go to sleep, once
the display turns off I cannot either ping or ssh into my gtablet?
So, I wonder if there is a way to do this.
(By the way, I assume that the wifi has power saving implemented
so just sitting around will actually not use much battery.)
I've noticed that when the screen goes off, adb even loses the tablet until you turn the screen back on. But I am having the same issues with Wifi, and setting it to never sleep in addition to installing a keep alive app doesn't seem to do much good. When the screen goes off for a couple of minutes, all connections seem to be lost.
It would be nice if there was some sort of solution to this.
yes, I can't get wifi to stay on. Basically, I want the tablet to stay
on but the screen to blank.
This is more important now that I have rsync installed and could
do automated data transfers or backups at scheduled times.
I am running Vegan 5.1.1 and am wondering this too, is it a vegan problem or gtab? Is there a dev that can make a kernal to stop this?
I am on a TnT ROM using Clemsyn's kernel, and I get the same problem, so it might be a device issue.
I'm trying out an app called Wifi Fixer -- free from the Marketplace (though I'll get the .99 cent donate version if this works). I left the tab display off and untouched for about 10 minutes just now, and wifi was still connected when I turned it back on. I'll let it sit for about 1/2 hour and see if it still works. If so, we might have a winner
In TNT (Lite), try Settings -- wireless -- Wi-Fi Settings -- Advanced Settings -- Wi-Fi Sleep Policy
wifi sleep policy is set so -- supposedly -- wifi never sleeps, but that did
not work for me (wifi was shut down when tablet goes to sleep - I wonder
what controls that - I would want display and system to have separate
sleep control ...)
But I found an app in market, wifi keepalive that seems to be working.
My tablet just turned off the display and I can still ssh, ping and rsync
successfully.
Maybe that is the solution.
I wonder how much power this will draw?
(I have a nokia n810 "mini-tablet" and even with wifi on (power saving
mode enabled) battery consumption is pretty minimal if wifi is not
actually in use. Does android use power saving mode in wifi?)
Well, I already had it set to never sleep. The Wifi Fixer seems to work though -- I let it sit for about 1/2 hour, and when I flipped it back on, the wifi was still connected.
Edit: Nevermind, that didn't work either. Sucks, I love this tablet, but if it's a dead fish when the screen is off for a few minutes, it's lost a good deal of usefulness to me.

That was the one I was using initially, but while it wouldn't drop the wifi connection upon turning off the screen, it would eventually drop it -- when I woke the tab back up, I'd have the wifi lost icon for a few seconds.

yep, it looks like that happened here too ... maybe some other
app is resetting this; it lost my connection after a radiotime
app was playing for about half an hour with screen off
I hear that ubuntu might run on this - it would be great to
have a **real** operating system to fiddle with
I like keeping my wifi on while my screen is asleep so that I can receive chat messages or e-mails without being at my computer. I never had this problem while running ICS on an unrooted TF201, but ever since I installed the upgrade to JB my wifi will always disconnect after the screen has been asleep for a few minutes. I've checked every setting I can think of. In the Wifi Advanced menu, I have it set so Wifi is always on, and in the ASUS customized setting I have Disconnect network during sleep to off. Under Power Saver I have Enable low battery settings off, set Low battery level to 0%, and even set Wifi OFF to off. Despite all of this, it seems like the tablet under JB goes into some sort of deep sleep and disconnects the wifi after about 5 minutes of inactivity.
I have noticed that this problem does not occur when the screen is on. I also have the dock, and set the screen to always on during meetings in the event that I don't need to enter any notes for a few minutes so I don't have to fool with any delays from screen wake .
Is there some setting I'm missing? Is it a hidden setting that I could access by rooting? Or am I dealing with something internal to the build that I can't change at all? This may not seem like a huge deal to most, but it has become one of my main uses for the tablet when I'm at home. I'm very disappointed with JB so far even though the wifi does feel more responsive on the Prime after the update (when it's not sleeping, of course!).
EDIT: I noticed this evening that the wifi turns off even when I'm running something that uses it while the screen is off. I was listening to Pandora, and about 5 minutes after the screen went off, my music stopped. When I turned the screen back on, I saw that the wifi had indeed become disconnected.
hey,
I have exactly the same problem with my tablet. I have checked every option, I did a factory reset several time, I have checked it on 2 different routers but it is still disconnecting the wife when it goes in the sleep modus. Did you or anyone else find a solution?
I have both of these setting turned on, but for some reason the bluetooth discoverability will dissapear every few hours for a few minutes, and the wifi seams to go to sleep after a certain amount of time (hours) after the screen is off. I imagine, particularly with the wifi that this might be done to conserve battery.
The reason I know this is that I use the phones bluetooth discoverability to determine whether or not I am at home or away, and trigger events accordingly through my home automation software. When the bluetooth mac address of my phone is not found to be present, a ping is sent through wifi as a fallback. However both are failing according to the logs. (not to mention all my lights and electonics turning off while watching a movie, or even worse the lights and electronics turning on at two in the morning as if I had just arrived home when actually I was asleep in bed)
I didn't have this problem with my OG EVO 4g, and so I am hoping there is a hidden setting or even maybe an app available that will hold these setting to do what they say, and not just use them as a suggestion. I understand the battery trade-off.
Edit: I am on a CM10 ROM, so I do not have smart sync
Well go to advanced in the WiFi and Bluetooth setting. And you'll see what to do when you get there

I already know what to do there (as is pointed out in the title of the topic), those are both enabled.
I am running Liquid Smooth 3.2 for months now. I format it regularly just to get a new sense of speed after downloading junk i shouldnt have to begin with. Recently i have been formating to fix my WiFi issue. It seems like when i connect wifi (turn it on) it simply doesnt connect (it doesnt turn from grey to white or blue) it just stays grey. WHen i look at the list of wifi available it says its connected but i receive no data. After a while it seems to syncronize and the wifi works. I used to think if i turn on 4g and wifi together it seems to speed it up. All speculation, the only fact is WiFi isnt working upon engaging it. Reboot fixes it untill i turn wifi off (or it the AP goes unavailable for extended period of time, it doesnt seem associated with turning it off and on.)
Any suggestions? I have tried backdating to .09 radio. It doesnt seem to fix it.
